8 Claims.

My present invention relates to a folded display portablepartition carton and blank therefor. The object of my invention is to eliminate disadvantages of present methods of shipping tin or case goods, and to provide means to pack articles such as cans, jars or other containers in a portable partition carton made from an integral blank.

The reason for the development of my present invention is that underpresent methods of packing case goods, particularly when packed in tins, it is impossible to deliver the packages in perfect condition. Cans or tins quite often reach the retail store in' a damaged condition. This is noticeable by the fact that the can is often dented, scratched, or otherwise mutilated in such a way that it is impossible to sell the can at regular retail prices, or that the contents are spoiled. Quite often the label is mutilated or completely torn away resulting in loss of attractive value or complete impossibility of sale due to lack of knowledge of the type of foodstuff enclosed. Dents in the tin or can sometimes result in such a change of pressure on the contents that the seams or joints are separated and the contents spoiled, not to mention the fact that leakage damages the labels of other cans.

My carton is made from an integral blank of cardboard, strawboard or other material, preferably of the type known as single or doublefaced kraft corrugated board, the latter material being strong, rigid and relatively thin for its stiffness. With my invention a maximum of protection is afforded the articles without appreciable waste of material or use of loose packings such as excelsior or sawdust. One feature of my invention is that each article is retained in a nest or compartment which prevents it from being damaged by knocking against others. The

rigid requirements of common carriers are fully satisfied by my carton.

My carton provides means for packing preferably two or three containers, a feature that is extremely desirable in stores which specialize in combination "package sales. In connection therewith my carton is so formed that a plurality of articles are packaged as one saleable unit which is easily grasped and carried away by' the customen' Articles so packaged are displayed to theconsuming'public while'retained in a neat carrying package.

A further object of my invention is to afford means for packaging articles without the use 'of expensive packaging machinery such as stapling or sewing units, my carton being selfretained without so much as an adhesive strip being required to seal it.

My invention is formed from an integral blank cut and creased in a 'press and shipped in fiat form to the user. An advantage of this form of carton is that the blanks may be shipped on common carriers under the rates applicable to flat sheets, which is lower than that imposed upon formed articles. Another advantage obtained by my invention is is formed Without appreciable waste, it being cut from a large sheet of material in such manner that the edges of each-blank form the edges of adjacent blanks without loss of material therebetween.

My carton is not limited to the packaging of tin goods, it being of such form that fragile containers such as are in common use are completely protected therein. The carton as formed is selfsustained and may be packed in tiers without crushing the enclosed articles, allowing the packaging of open trays or baskets of fruit, berries or even short stemmed flowers. Bags of nuts and other commodities may likewise be shipped in my carton without danger thereto.

The preferred form of my invention is illustrated in the accompanyingdrawing and a detailed description thereof given in the following specification.

Referring to the drawing wherein like numerals refer to like parts:

Figure 1 is a plan view 0 to the consumer,

Figure 2 is a perspective view of the assembled carton,

Figure 3 is a sectional view of the carton taken along line 3--3 of Figure 2, showing an enclosed article in skeleton outline, and

Figure 4 is a partial perspective of the blank with the partition flaps assembled.

the blank as shipped Figure 1 illustrates the blank showing the relatively small percentage of waste involved in cutting it from a large sheet of material The bottom of the carton is indicated at I, side walls 2 and 3 being attached thereto along score lines 4 and 5 respectively. Top flaps. 6 and 1 are attached to side walls 2 and 3 respectively along score lines 8 and 9. The'end edges of flaps 6 and l are cut away on lines Ill and H, the cuts beginning at diagonally opposed corners of the flaps and extending inward to median points thereof. Locking tabs I2 and I3 extend past the median toward these same corners and are spaced from cuts l0 and II by notches l6 and I5. Side walls 2 and 3 have tabs I6 and ll formed therein, said tabs being triangular in shape and formed by diverging cuts along two sides thereof, the divergent ends of the cuts being joined by score lines parallel to score lines 8 and 9.

A set of tray-forming members are attached to bottom I along score lines 20 and 2|. These members consist of end flaps 22 and 23, and side flaps attached thereto along score lines parallel to, but slightly inward from, score lines 4 and 5. Side fiaps 24 and 25 are connected to end flap 22, and side flaps 26 and 21 to end fiap 23. The

side flaps are separated from the side walls by straight cuts 28. Rounded portions may be removed from the side walls by cutting along lines 29 if desired, for a purpose which will be explained. Side flaps 24 and 21 are identical in shape and form, but are diagonally opposed so that side flap 21 is adjacent to side wall 2, while side flap 24 is adjacent to side wall 3, and each flap has a notch 30 therein extending from a median point into cut 28. Side fiaps 25 and 26 are identical but diagonally opposed, and have partition flaps 3| attached thereto along score lines, and notches 32 extending from a median point to their outer edges.

The blank having been sufficiently described the method of assembling it into the carton will now be set forth. End flaps 22 and 23 are first bent upwardly along lines 20 and 2|. Side walls 24 and 26 are now bent inward, parallel to line 5 but slightly inwardly thereof, flap 24 being outside of and overlying flap 26. The end of flap 24 is now brought inward, notches 30 and 32 registering and locking the flaps together. This process is repeated with flaps 25 and 21, flap 25 being locked inward of fiap 2I by the registering of notches 30 and 32 therein. Partition flaps are now bent normal to flaps 25 and 26, the flaps being brought into such relationship that each opposes the normal tendency of the other to resume a position in a straight line with its attached side fiap.

It is apparent that there is now formed a shallow tray having a plurality of nests formed therein, each nest being adapted to receive therein a single article and restrain it from contact with others. It is equally apparent that members 3| may be so bent by' the carton assembler that three nests or compartments are formed, each nest being defined by one of the partition-forming members instead of the two combined as in Fig. 4.

The carton may be so proportioned that the enclosed articles are of the same height as the assembled carton (such as the articles shown at Figure 3) and should now be placed in the nests of the tray. Partition members 3| prevent the articles from knocking together and breaking. If the articles are of a lesser height they can easily be inserted later, their presence not being necessary to retain the carton as formed; 5 Side walls 2 and 3 are now bent upward along score lines 4 and 5 enclosing the tray therein, and top flaps, 6 and I are bent inward along lines 8 and 9. By a simple twist of the top flaps and side walls, locking notches l4 and 5 are interengaged, locking tabs l2 and I3 underlying the oppositetop-flaps I and 6 respectively and cuts l0 and form a straight continuous diagonal line across the top of the carton as seen in Fig. 2. The locking tabs l2 and i3 are thus protected from accidental tearing or disengagement and the outside surface is neat and unmarredby irregular lines.

Wall of the carton prevents the containers fromtilting and falling out through the open display ends while partition members 3| and tabs I6 and I! prevent lateral shifting of the containers toward each other. End flaps 22 and 23 "effectively prevent lateral shifting of the containers through the open display ends of the carton.

The inherent stiifness of the material retains the carton so locked and it is impossible for the tabs to, be accidentally released, yet a simple twist of the side walls and top flaps will open the carton when desired.

The package so formed makes an eficient display unit, both enclosed articles being open to view. The cutaway portions 29 enhance this feature, but the ends of sides 2 and 3 may be straight if desired.

Articles when sold in this manner do not need to be wrapped or placed in bags but can be carried away as they are simply by placing the hand over the carton and gripping its sides. The fingertips may be engaged in the openings left by the inward displacement of tabs l6 and 1, thus preventing slippage and assuring a firm grip. This feature is equally present where the usual round type of container is not enclosed, the tabs usually give sufliciently to allow a slight inward bulge below the attaching score lines thereon which will form a hold for the fingertips.

Larger articles may be packed in cartons of larger dimensions, flaps l6 and H in such case afiording a hand hold on either side of the carton. The sides and top of the carton may carry printed matter or labels and the carton may be wrapped in cellophane or other transparent material'.

As is obvious to those skilled in the art my invention may be modified and the several parts rearranged without departing from the spirit of my invention, the scope of which is set forth in the following claims which are to be construed broad- -ly. In using the terms end, side" and bottom in the appended claims, it is not intended to limit tached to each side wall along a score line, the

edge of one top fiap being cut diagonally inwardly along a line from one corner to a median point and to form a tab extending from said median point toward said corner, the edge of the other flap being cut diagonally inward along a line from the corner diagonally opposed to said first corner to a median point and to form a tab exshallow tray having article-retaining compartments, side walls integral with the bottom of said tray and extending to a greater height than said tray, the end edges of said side walls being cut away to afiord a greater display of enclosed articles.
